I. SAFETY
Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules
included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe
place for further reference. In order to avoid accidents and errors it should be ensured that every person using the device
has familiarized themselves with the principle of operation as well as security functions of the controller. If the device is
to be sold or put in a different place, make sure that the user’s manual is there with the device so that any potential user
has access to essential information about the device.
The manufacturer does not accept responsibility for any injuries or damage resulting from negligence; therefore, users
are obliged to take the necessary safety measures listed in this manual to protect their lives and property.
WARNING
High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving
the power supply (plugging cables, installing the device etc.).
The device should be installed by a qualified electrician.
Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the
insulation resistance of the cables.
The regulator should not be operated by children.
NOTE
The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply
during storm.
Any use other than specified by the manufacturer is forbidden.
Before and during the heating season, the controller should be checked for condition of its cables. The user
should also check if the controller is properly mounted and clean it if dusty or dirty.

III. HOW TO INSTALL THE CONTROLLER
The controller should be installed by a qualified person.
WARNING
Risk of fatal electric shock from touching live connections. Before working on the controller switch off the power
supply and prevent it from being accidentally switched on.
VER-24 WiFi regulator is intended to be installed on the wall.
First, attach the back cover to the wall in the place where the room regulator in the electrical box will be installed. Next,
connect the power supply wires and mount the device on the latches.

IV. PRINCIPLE OF OPERATION
VER-24 WiFi controls the fan and the valves in order to maintain the pre-set room temperature. Depending on selected
operation mode, the device may increase the temperature (heating mode) or decrease the temperature (cooling mode).
It controls smoothly the fan operation (increasing or decreasing its speed when needed) and the valve operation
(increasing or decreasing the level of valve opening depending on current needs). Additionally, the device may be used
to control another valve by opening it or closing as needed.
V. MAIN SCREEN DESCRIPTION
The main screen displays current status of basic controller parameters.
1. Day of the week and time
2. Current operation mode. This icon may also be used to change the operation mode:
- Heating–sun icon
- Cooling –snowflake icon
NOTE
This function is active when Manual heating/cooling option is selected in the service menu, in Mode selection
submenu.
3. Current controller operation profile
4. WiFi signal
5. Enter the controller menu
6. Current pre-set temperature (depending on selected profile and operation mode)
7. Fan mode change icon. The fan may operate in the following modes:
- Automatic –the fan speed is controlled with the controller operation algorithm
- Manual –three speed levels

- BOOST - the pre-set temperature will be reached in the shortest possible time. When the operation time is over
or the pre-set temperature has been reached, the fan will enter automatic operation mode.
- OFF
NOTE
Information about current fan operation mode is saved in the controller memory 6 seconds after the last
parameter change.

VI. CONTROLLER OPERATION MODES
Regardless of the selected profile, the controller may operate in three modes: heating, cooling or automatic
heating/cooling. In Service settings/Mode selection submenu the user configures particular mode. The user may select
one operation mode - by selecting Heating or Cooling or allow manual mode change from the main screen view - by
selecting Manual heating/cooling.
Heating
Once this mode has been selected, when the controller detects that the room temperature is lower than the pre-set value
(setting in Temperature settings submenu), it activates the fan and opens the valves in order to raise the temperature.
When the room temperature reaches the pre-set value minus user-defined value (setting in Service menu/Temperature
settings), the controller gradually starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
Cooling
Once this mode has been selected, when the controller detects that the room temperature is higher than the pre-set
value (setting in Temperature settings submenu), it activates the fan and opens the valves in order to decrease the
temperature. When the room temperature drops to the pre-set value plus user-defined value, the controller gradually
starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
Automatic heating/cooling
The heating mode changes automatically depending on the current room temperature and the pre-set value.
VII. CONTROLLER FUNCTIONS
During standard controller operation, the display shows the main screen. By pressing menu button the user may configure
the controller functions.
Due to the controller complexity (a wide range of configurable parameters), the controller menu is divided into the main
menu and the service menu secured with a 4-digit code. The main menu includes basic controller parameters such as
operation mode, pre-set temperature setting, main screen view etc.

2. WIFI MODULE
The controller features a built-in Internet module enabling the user to monitor the status of all system devices on a
computer screen, a tablet or a mobile phone.
Apart from the possibility to view the temperature of every sensor, the user may adjust the pre-set temperature values.
After switching the module on and selecting DHCP option, the controller automatically downloads such parameters as IP
address, IP mask, gateway address and DNS address from the local network. If any problems arise when downloading the
network parameters, they may be set manually.
3. PROFILE SELECTION
The parameters in this submenu are used to select the controller operation profile.
The profiles offered by the controller are used to maintain the room temperature at a pre-defined level. The user may
choose from 3 profiles (comfort, eco, protection), 3 daily schedules (1,2,3) and a weekly schedule.
COMFORT - In this profile the user defines one pre-set temperature (SetT) in Temperature settings, fig.1,2. In
case of room temperature decrease (heating mode) or increase (cooling mode) by 0.1 °C, the controller starts
opening the valve gradually and the fan is enabled. If the temperature continues to fall (heating mode) or grow
(cooling mode), the controller will gradually open the valve. Below the pre-set temperature SetT - delta (or above
the pre-set temperature SetT+ delta) the valve will be completely open. Figure 1 illustrates the fan operation.
